How robust are gravitational wave predictions from cosmological phase transitions?
Peter Athron, Lachlan Morris, Zhongxiu Xu
Gravitational wave (GW) predictions of cosmological phase transitions are almost invariably evaluated at either the nucleation or percolation temperature. We investigate the effect…
Can supercooled phase transitions explain the gravitational wave background observed by pulsar timing arrays?
Peter Athron, Andrew Fowlie, Chih-Ting Lu +4
Several pulsar timing array collaborations recently reported evidence of a stochastic gravitational wave background (SGWB) at nHz frequencies. Whilst the SGWB could originate from…
Cosmological phase transitions: from perturbative particle physics to gravitational waves
Peter Athron, Csaba Balázs, Andrew Fowlie +2
Gravitational waves (GWs) were recently detected for the first time. This revolutionary discovery opens a new way of learning about particle physics through GWs from first-order ph…
